Spark is Now Generally Available for Cloudera Enterprise

Cloudera is announcing the general availability of support for Spark, bringing interactive machine learning and stream processing to enterprise data hubs.
Cloudera is pleased to announce the immediate availability of its first release of Apache Spark for Cloudera Enterprise (comprising CDH and Cloudera Manager).
Spark was created and contributed to the Apache Software Foundation by UC Berkeley, and it has quickly gained adoption for machine learning, interactive analytics, and streaming analytics over large datasets. It features a general programming model for writing applications by composing arbitrary operators, such as mappers, reducers, joins, group-bys, and filters. Spark keeps track of the data that each of the operators produces, enabling applications to reliably store this data in memory, which makes it ideal for low-latency computations and efficient iterative algorithms. Spark applications can be up to 100x faster and require writing 2x to 10x less code than equivalent MapReduce applications.
